TAPE DELIVER ING MACHINE I Filed Dec. 2, 1927 4 Sheets-Sheet 3 InventorG. Remn snider Patented Apr. 7, 1931 rra GEOEGE REMNSNIDERI, FBELLEVILLE, ILLINOIS TAPE-DELIVERING MACHINE Application filed December'2, 1927. Serial No. 237,189.

My invention relates to a tape delivering machine and particularly toone for delivering and at the same time moistening gummed tape, such asis used for sealing cartons,

bundles, etc.

' @ne of the objects of my invention is to provide a machine in whichthe delivery of the tape is controlled by a handle in such manner thatstrips of any desired length within to the capacity of the machine maybe delivered without special setting of the machine by observing asuitable indicating device.

Another object of my invention is to provide means for severing the tapeby a reverse movement of the handle; and still another object is toprovide improved means for holding and centering the tape roll.

My invention also has for its object the provision of various new andimproved details of construction as hereinafter set forth.

In theaccompanying drawings, which illustrate one form of machine madein accordance with my invention, Figure 1 is a top plan view, the rollerguard being removed; Figure 2 is an enlarged section taken on the line22 of Figure 7; Figure 3 is a section taken on the line 33 of Figure 5;Figure 4 is a section taken on the line 4-4- of Figure 1; Figure 5 is asection taken on the line 5-5 of Figure 6; Figure G is an enlargedsection taken on the line 66 of Figure 4; Figure 7 is a view partly inside elevation and partly a section takenon the line 7-7 of Figure 1;Figure 8 is an enlarged detail of some of the parts hidden in Figure 7;Figure 9 is an enlarged section taken on the'line 99 of Figure 11;Figure 10 is a plan view of the clutch shown in Figure 9; Figure 11 isan enlarged side elevation of the front part of the machine taken fromthe side opposite Figure 7, the gear cover plate being removed andFigure 12 is a section taken on the line 1212 of Figure 11.

The framing of the machine comprises a right hand casting 1 and a lefthand casting 2 terminating at their forward ends in flanged circularplates 3 and 4, respectively, and provided with feet 5 upon which themachine is supported. Extending between plates 3 and 4, and securedthereto by bolts 6, is a U-shaped frame formed of a pair of side plates7 and a bottom plate 8, which frame serves not only to space the plates3 and a apart, but, also to carry the tape-clipping mechanismhereinafter to be described. A central cross-rod 9 spaces the rear endsof the castings 1 and 2 apart and together with a pair of cross-rods 10arranged one at the front and the other at the rear of the rod 9, formsthe support for the roll carrying mechanism. Secured to the plate 3 is acover 11, and to the plate 4 a cover 12.

The main or driving shaft 13 is journaled in the plates 3 and 4C andprojects at the right hand side through an opening in the cover 11, asshown in Figure 2. Non-rotat-. ably mounted on the shaft at the. end isa sleeve 14, and on the sleeve a handle 15. Rigidly mounted on the innerend of the sleeve 14 are a pair of ratchet wheels 16 and 17 having theirteeth arranged in reverse directions and between them is loosely mounteda gear wheel 18. Carried on the gear wheel is a spring pawl 19 engagingwith the ratchet wheel 16 so that, when the handle is rotated inaforward or clockwise direction the wheel will move with it but willremain stationary when. the handle is reversed. Meshing with the wheel18 is a pinion 20 on the end of a shaft 21 carrying a feed roll 22.Cooperating with the feed roll 22 is a second and smaller feed roll 23journaled in the horizontal arms of bell-crank levers 24: mounted onstuds in the plates 3 and 4. Adjustable screws 25 carried by thevertical arms of theselevers project rearwardly through a tape guide 26and are surrounded by coil springs 27 which tend to move the armsrearwardly and thus hold the roller 23 in yielding contact with theroller 22. The right hand trunnion of the roller 23 extends through anopening 28 (shown in dotted lines in Figure 7) in the plate 3, whichopening is of larger diameter than the trunnion to allow the slightrelative movement of the feed rollers to accommodateflvaryingthicknesses of tape. Mounted on the end of the trunnion is a pinion 29meshing with a gear Wheel 30 on the shaft 21. The pitch lines of thepinion 29 and gear 30 correspond with the diameter of the feed rolls sothat these are driven at the same peripheral speed. Meshing with thegear 18 is a second pinion 31 on the end of a shaft 32 carrying a roll33 acting both as a feed and moistening roll. Cooperating with this rollis a roll 34 journaled in arms 35 mounted on studs in plates 3 and 4.This roll bears on the roll 33, or on the tape passing between therolls, by gravity and is driven by friction alone.

The detachable water pan 36 is held against lugs on the plates 3 and 4by the conical end of a screw 37 bearing against the bottom of the panand a lug 38 thereon and threaded in a U-shap-ed bracket 39 looselymounted on a rod 40. This rod eX- tends between the castings 1 and 2 andin addition to carrying the bracket serves as a spacing member. Byretracting the screw out of contact with the pan the bracket may heswung away from the pan so that the latter may be removed for cleaning.Riveted, or otherwise secured to the bottom of the pan, is a curvedstrip 41 of thin spring metal to which is secured a strip 42 of felt,wicking, or other capillary material for applying the water in the.panto the periphery of the rollerin a thin film. Water is introducedinto the pan by means of a hinged cover 43 which carries a strippingfinger 44, the pointed end of which projects into a central groove 45 inthe periphery of the roller to insure the detachment of the tape fromthe roller.

Formed in the plate 8 is a slot for the passage of the clipping knife 46which is shaped as shown in Figure 6 soas to make a double shearing cutbeginning at each side of the tape and terminating at the center. Thisknife is secured to a frame 47 slidingly mounted on aguide rod 48 andnormally held in raised position by a coil spring 49 surrounding saidrod. Secured to the bottom of the piate 8 is a guide plate 50 and asecond guide plate 51 separated from the said plate 8 by spacing strips52 (shown in detail in Figure 3) to form guide passages for the tape,first from the rollers 22 and 23 to the knife, and secondly from theknife to the rollers 33 and 34. On the rear edge of the plate 50 is aninclined lip cooperating with the rounded rear edge of the plate 8 toform a receiving mouth for the first guide passage and on the plate 51 asimilar lip cooperating with the beveled edge of the slot of the plateSto form a receiving mouth forthe second guide passage. The side plates7 carrying the plate 8 are so shaped as to form supports for theremovable roller guard 53.

Journaled in the plates 3 and 4 is a rock shaft 54 provided with acentral arm 55 connected by links 56 to the knife frame 47. Secured tothe right hand end of this rock shaft is a second arm 57 (Figure 7) towhich is pivoted a knuckle 58 normally held against a shoulder on saidarm by spring 59. On the inner face of the knuckle 58 is a roller 60(see also Figure 2). This roller is adapted to contact with the upperrounded face of a cam 1 when said cam is moved in a forward or clockwisedirection, in which case the;

knuckle is swung upwardly on its pivot against the tension of the spring59 without moving the rock shaft 54. Upon the return movement of the camthe lower inclined face engages the roller depressing the knuckle andwith it the arm 57 thus rocking the shaft 54 to actuate the knife 46 toclip the tape. The cam is carried on a plate 62 loosely mounted on theshaft 13 and having pivoted to it a pawl 63 engaging with the ratchetwheel 17. The pawl is held in engagement with the ratchet wheel by thecoil spring 59 extending between it ant. the knuckle. Movement of theplate 62 is limited in one direction by stop 64 and in the other by stop65.

Rigidly secured on the left hand end of the shaft 13 is a collar 66(Figures 9, 10 and 11) having a hub 67 on which is loosely mounted apinion wheel 68. A second collar 69 is also rigidly mounted on the shaftwith a loose collar 70 between it and the pinion. Formed on the opposingfaces of the collars 69 and 7 O are crown teeth 71. When the collar 69is rotated in the direction indicated by the arrow in Figure 10 and therotation of the collar 70 is retarded these teeth will act as cams toforce the collar 70 toward the end of the shaft and thus clamp thepinion between the said collar and the collar 66, while a slightmovement in the reverse dimotion will allow the collar 70 to recede andrelease the pinion. The device thus forms a quick acting clutch andrelease mechanism. In order to retard the collar 70 I pivot to bosses 72on the plate 4, by means of screw studs 73, a pair of lever arms 74carrying at the upper ends friction blocks 75 bearing on v the collar.In the drawings I have shown these blocks in the form of fiber disks,their shape, however, not being of importance as I theydo not revolvebut simply act as brakes. The lower ends of the arms terminate inrounded fingers 76 between which is a wedgeshaped member 77 the act-ionof the inclined faces of which on the fingers holds the friction blocksagainst the disk. Mounted on one of the studs 73, at the rear of thelever 74, is a double bellcrank lever 78 tocne arm of which the member77 is pivoted. A coil spring 79 is attached to the second arm of areloosely mounted a pair of gear wheels 83 and 84, the outer wheel 83meshing with the pinion 68. Situated between the wheels 83 and 84 andrigidly secured to the former, is a smaller wheel 85 meshing with awheel 86 mounted on a screw stud 87 in a boss 88. Rigidly secured to thewheel 86 is a second small Wheel .89 which meshes with the wheel 84.These wheels act as a reducing train of gearing for the indicating arm90 which is secured to the rear face of the wheel 84. This arm extendsthrough slot 91 (Figure 1) formed by cutting away a portion of the cover12 throughout an arc of somewhat less than 180 degrees. A pointer 92,formed by bending over the end of the arm, cooperates with a scale 93secured to the cover adjacent to the slot. Pivoted to the rear face ofthe wheel 84 by a screw 94, preferably at the point where the arm 90 isattached, is a link 95, pivoted to a lever 96 carried on a stud 97 inthe plate 4. A spring 98 attached to the lower end of the lever 96normally holds the indicator-arm against the upper end of the slot 91.

The tape roll 99 (Figure 7) is carriedbetween a pair of sliding frames100 each provided on the inner face with a boss 101 adapted to enter theusual hole on the center block on which the roll is wound. Each of theframes is provided with a short central bearing 102 engaging the rod 9and with a. long side bearing 103 engaging with one of the rods 10.Pivoted in each of the bearings 103 is a stud 104 in which slides a bar105 rigidly secured in a stud 106 passing down through the rod 9 andprovided on its lower end with an arm 107. Pivoted in the. end of thearm 107 is a stud 108 carrying a rod 109 surrounded by a coil spring 110and extend ing through the casting 1. The tension of the spring 110tends to move the arm 107 toward the left (Figure 1) and thus force theframes 100 toward each other. To insert a roll of tape in the machinethe rear end of the bar 107 is forced toward the right against thespring 110 until the frames 100 are separated a sufficient distance toallow the roll to enter between the bosses 101 until the hole in thecenter block is in alignment with said bosses when the bar is releasedso that the spring causes the frames to move toward each other, thebosses entering the center hole and the frames bearing against the endsof the roll. The device thus automatically adjusts itself to the widthof the tape used and accurately centers the roll of tape in the machine.The pressure of the frames on the ends of the roll also acts as a braketo preventthe over rotation of the roll as the tape is unwound.

The-operation of my machine is as follows: the end of the tape from theroll 99 is passed down over the guide plate 26 and between the feedrollers 22 and 23. Rotation of the handle 15 in a clockwise directionrotates the wheel 18 through ratchet wheel 16 and pawl 19, thus drivingfeed rollers 22 and 23 as well as feed roll 33. Friction of the pawl 63on the ratchet wheel 17 carries the plate 62 forward until it engagesthe stop the handle. lows further 65. During thismov'ement the knuckle58. is forced upwardly on its pivot by the engagement of the upper faceof the cam block 61 block clutches the pinion 68 so'that'the movementof. the shaft is communicated through the reducing gearing to theindicating arm which is thus caused to movealong the scale 93 toindicate the length of the tape unwound from the roll. When the desiredlength of tape is indicated on the scale 93 the direction of relation'of the handle 15 is reversed. As soon as the directionof ro-' tation ofthe shaft 13 is reversed the pressure of the collar 70 on the pinion 68is relieved so that the spring 98 acting throughlever 96 and link mayreturn the indicator arm 90 to its initial position shown in Figure 1.'The reverse movement of the handle is communicated through; ratchetwheel 17 and pawl 63 to plate 62 causing the lowerincline'd face of thecam block 61 to engage, with the roller 60 on the knuckle 58, thusdepressing the latter and consequently actuating the rock shaft 54. Themovement of this shaft communicated through arm 55 and links 56depresses the knife 46 to clip the tape. When the cam block 61 haspassed the roller 60 allowing spring 48 to return the tape clippingmechanism to normal position, the plate 62 will come into contact withthe stop 64 thus arresting the reverse movement of the handle. The tapemay now be grasped and its short end extending from the rollers 33 and34 to the knife be drawn over the now stationary roller 33 as it is heldagainst said roller only by the weight of the roller 34.

. The above is the operation of the machine when lengths of tapeno-longer than that indicated by the scale 93 are delivered. Greaterlengths may be delivered by a continued rotation of the handle. In thisevent when the indicator-arm has reached the lower end of the slot thescrew 94 will contact with the cam end 80 of the bellcrank lever'7 8 andthus raise the wedge member 77 and relieve the pressure of the frictionblocks 75 on the roller 7 0. The clutchmechanism will thus be releasedand will not interfere with the further rotation of the handle.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is:
